Title: Bipolar transistor and manufacture thereof
Inventor: EDA KAZUO
IPC: H01L29/73
Filed: 1995-11-27
Abstract: PROBLEM TO BE SOLVED: To restrict the drop in base-emitter voltage by forming a base region that includes a polycrystalline or amorphous silicon region to limit the increase in base resistance with rising temperature. SOLUTION: A polycrystalline of amorphous silicon region 11 is formed in part of the base region 4 of a bipolar transistor on a silicon substrate 2. The polycrystalline region 11 makes no contact with the base electrode 9 or the emitter region 5 in the base region 4. As the temperature of the silicon substrate 2 rises, the resistance Rc of the single-crystal silicon region extending from the base region 4 below the emitter region 5 to the polycrystalline silicon region 11 increases, but the resistance Rb of the polycrystalline region 11 decreases. This restricts the increase in base resistance with the rise in temperature of the silicon substrate 2.
